David Brown – other models: the collective page of British tractors outside the named ranges, from the Cropmaster and the 850/880 Implematic to the 990 and 1210, 24.5 to 67 kW, three- to six-cylinder diesel engines
This page gathers the David Brown tractors the register could not assign to a named range – the British marque from Meltham near Huddersfield that grew out of a gear works and, together with Harry Ferguson in 1936, developed the first series-built British tractor with hydraulics, before the two parted ways in 1939 and David Brown began building its own tractors. The Cropmaster of the early 1950s is regarded as one of the first tractors with a factory-fitted driver's cab; the 900 series brought the Implematic three-point hydraulics with draft control, marked by the Implematic suffix on the 850 and 880 types. The four-digit type logic of the 1960s and 1970s orders the range in the first digit, while the number after the slash (880/1910, 990/2000) states the gearbox or hydraulics variant and the year of revision; in 1965 the British Tube Investments group took the majority stake, and in 1972 David Brown finally sold the tractor division to the American J.I. Case, which continued the brand into the late 1980s.

The register lists here 28 versions with 24.5 to 67 kW from three- to six-cylinders of 2,520 to 5,390 cm³ displacement, unladen weights from 1,580 to 4,210 kg, gross weights from 4,000 to 9,500 kg and torque from 169 to 314 Nm at 2,000 to 2,300 rpm.
David Brown was, into the 1970s, one of the major British tractor makers alongside Ford and Massey Ferguson, and shaped post-war British tractor building with the Implematic hydraulics and the Cropmaster's early factory cab.
On used examples, the condition of the gearbox and clutch, the tightness of the Implematic hydraulics, rust on mudguards and bonnet, the state of alternator and starter motor, and on the older models the availability of gaskets count; parts are carried by specialist dealers in classic British tractors and the Case IH network.

What to check before buying
- Check the hour meter against the service records — a replaced instrument is the most common gap.
- Compare the data plate and chassis number with the papers.
- Check the weights in the papers against the figures here — attachments change them.
- Load the hydraulics and watch for sag.
- Ask about parts availability for this build year — the running costs hang on it.
